,Analog A way of representing some physical quantity, such
as temperature or velocity, by a proportional
continuous voltage or current. An analog voltage or
current can have any value within a defined range.
AND Gate Digital circuit that implements the AND operation.
The output of this circuit is HIGH only if all of its
inputs are HIGH.
Breadboard A circuit board for wiring temporary circuits, usually
used for prototypes or laboratory work.
Capacitor An electrical device used to store electrical charge.
Combinational Logic Digital circuitry in which an output is derived from the
combination of inputs, independent of the order in
which they are applied.
Conventional Current The direction of current flow associated with positive
charge in motion. The current flow direction is from a
positive to negative potential, which is in the
opposite direction of electron flow.
Current A movement of electrical charges around a closed
path or circuit.
Cycle A series of events that are regularly repeated in the
same order.
Datasheet A printed specification giving details of the pin
configuration, electrical properties, and mechanical
profile of an electronic device.
, Digital A way of representing a physical quantity by a series
of binary numbers. A digital representation can have
only specific discrete values.
Digital Multi-Meter(DMM) A piece of test equipment used to measure voltage,
current, and resistance in an electronic circuit.
Engineering Notation A floating point system in which numbers are
expressed as products consisting of a number
greater than one multiplied by an appropriate power
of ten that is some multiple of three.
Fuse A protective device in the current path that melts or
breaks when current exceeds a predetermined
maximum value.
Kirchhoff's Current Law (KCL) The algebraic sum of all currents into and out of any
branch point in a circuit must equal zero.
Kirchhoff's Voltage Law (KVL) The algebraic sum of all voltages around any closed
path must equal zero.
Large Scale Integration (LSI) An IC that contains circuitry equivalent to 100 gates
or more.
LED Light-emitting diode. An electronic device that
conducts current in one direction only and
illuminates when it is conducting.
Logic Gate An electronic circuit that performs a Boolean
algebraic function.
Logic HIGH The higher of two voltages in a digital system with
two logic levels.
Logic LOW The lower of two voltages in a digital system with two
logic levels.
